4 Claims. 1

My invention relates to strike plates to be used in connection with doorframes, and has specific relation to an improvement in such plateswhereby adjustments may be made from time to time to prevent doors fromrattling.

An important object of my invention is to provide a strike plate of theaforementioned character which has an opening to receive the springurgedlatch structure on a door; the said strike plate being provided with aright angularly formed lug interiorly of the said opening, and which ismaintained in adjustment by set screw means having its tip abutting themortised portion in the door frame.

Another object of my invention is to provide a strike plate havingadjustment means, as hereinbefore described, made of a single piece.

A still further object of my invention is to provide a strike plate ofthe aforementioned character which is practical, and of such simpleconstruction as to warrant economical manufacture thereof in quantityproduction.

Other objects, ancillary advantages, and features resident in myinvention. will become apparent from an examination of the accompanyingdrawings, bearing further elucidation in the ensuing description whereinlike symbols are used to designate like parts, and in which:

Fig. l is a perspective view of a door frame portion with my strikeplate attached thereto; portions being broken away in section in orderto more clearly depict the structural features of my invention.

Fig. 2 is a front view of the strike plate cornprising my invention.

Fig. 3 is a, cross-sectional view taken substantially on the line 3-3 ofFig. 2.

Fig. 4 is an end view of Fig. 2.

Referring to the drawings, my invention is generally designated 5 and isattached by screws, or other means not shown, to the said door frame 6;an abutting or stop ledge 'l is secured as indicated providing theabutment or stop surface B against which the surface 9 of the door I4will rest when closed.

The latch structure 2l, which is usually mounted in suitable mechanismand is spring urged, is provided with a cam surface 23 and the abutmentsurface 22. The strike plate consists of an elongated iiat supportingportion I having an elongated extension II, and a bolt or latchreceiving opening I2. On one side of the said latch receiving opening, alug portion I 6 is formed at right angles to the surface I0. The saidadjusting lug I 6 is provided with a threaded hole in order to exertpressure against the surface 2Q of the mortise 25. Thus it can be seen,as shown in Fig. 3 that the adjustable lug I6 may assume variedpositions indicated by the dotted lines in Fig. 3, and thus tend toconne the door I4 so that its surface 9 will rest against the stop edge8 of the abutting ledge or stop l. The forward portion of the strikeplate is bent as indicated at I3 in order to provide suitable clearancefor the edge I5 of the door when swinging into locking engagement.

The strike plate portion I I is partially curved, or bent, as indicatedat I3 in order to afford suitable clearance for the edge I5 of the doorI4 when swinging into closed position. The cam surface 23 thus willcause the latch ZI to move inwardly against the spring tension providedtherefor, and allow the same to escape subsequently, so that its flatsurface 22 will abut the forward surface of the adjusting lug I6, thusmaintaining the door confined against movement between the lefthandsurface of the adjusting lug II and the abutting surface 8 of theabutment ledge l.

If the door shrinks and rattles, then the adjusting lug IB is adjustedto some such position afforded by the range of flexure provided by thedotted line indicated in Fig. 3. By rotating the screw I8, pressure isexerted against the surface 20 to cause an adjustment to take place tomake the door I4 rattle-proof. Likewise, if the door should swell forany reason, then the adjustment screw I8 may be loosened allowing theadjustment lug I6 to assume its normal position thereby providing agreater increment of space between the stop portion 8 and the left-handsurface of the adjusting lug I6, permitting adjustments to be made underclimatic conditions when doors are apt to either shrink or swell, andthus the device comprising my invention will accommodate and aid inrectifying such conditions that might arise due to climatic'changes.Thus it can be seen that I have provided an improved strike plate whichis also anti-rattle.

Although I have herein described rather succinctly the nature and use ofmy invention so that persons skilled in the art will have no difficultyapprising themselves of the teachings thereof and, inasmuch as thedisclosure is susceptible of various alterations, modifications, andimprovements, I hereby reserve the right to all modiiications,alterations, and improvements falling Within the scope and spirit of myinvention, as well as any modifications that are embraced suggestivelyin the accompanying drawings, and any that may come within the purviewof the foregoing description; my invention to be limited only by theappended claims.

Having thus disclosed and revealed my invention, what I claim as new andldesire to secure by Letters Patent is:

1. A strike plate made of one piece of material for a door frame havinga mortised opening, com.- prising a plate element consisting of anelongated supporting portion merging with 4extension, a latch receivingopening in the said elongated supporting portion andY contiguous to thesaid extension and in registry with the said mortised opening, anadjusting lug portion adjacent the said latch receiving opening and inright angular relationship to the said extension, and adjusting screwmeans secured ,substantially perr pendicularly to the said adjusting lugportion its free terminus abutting a face Within the interior confinesof the said mortised opening for urging the said adjusting lllgpoltionin order to lalter the right angular relationship thereof.

2. A strike platemade'of one piece 0i material for a door framev havinga mortised opening, comprising a plate element consisting of anvelongated supporting portion merging with an extension, a latchreceiving opening in the said elongated supporting portion andcontiguous to the said extension and in registry with the said mor,-tised opening, a resilient adjusting lug portion adjacent the said latchreceiving opening and in right angular relationship to the saidextension, and adjusting screw means secured substantiallyperpendicularly to the said adjusting lug portion its free terminusabutting a face Within the interior confines of the said mortisedopening for urging the said adjusting lugr portion in order to alter theright angular relationship thereof.

V3. A strike plate made of one piece of material for a door frame havinga mortised opening, comprising a plate element consisting of anelongated supporting portion merging with an extension, a latchreceiving opening in the said lelongated supporting portion andcontiguous to the said extension and in registry with the said mortisedopening, an adjusting lug portion adjacent the said latch receivingopening and in right angular relationship to the said extension,adjusting screw means secured substantially perpendicularly to the saidadjusting lug portion its free terminus abutting a face Within theinterior confines of the said mortised opening for urging the saidadjusting lug portion in order to alter the right angular relationshipthereof, the said adjusting means, including -a threaded opening in thesaid adjusting lug portion, and screw means threadably and adjustablyengaging the said threaded opening, the tip of the said screw restingagainst a face of a mortised opening in a door frame..
